Allen-Bradley 100-D420EA00 Bulletin 100-D: 3-Pole Non-Reversing Contactor, 8–10×Ie Breaking Capacity, 2000m Altitude Rated

Technical Specifications

Main Features and Advantages

Electronic coil with integrated PLC interface:The defining innovation of the Allen-Bradley 100-D420EA00​ is its EA-type electronic coil, which fundamentally re-engineers how a 420 A contactor is controlled. Unlike conventional AC electromagnetic coils that demand a massive inrush current (often > 400 VA) and sustain high holding power throughout operation, the electronic coil of the Allen-Bradley 100-D420EA00​ delivers low, stable power consumption—approximately 490 VA peak inrush dropping to just ~7 W holding power. Critically, the electronic coil incorporates a built-in PLC interface, enabling direct connection to PLC digital output modules or solid-state relays without intermediate power amplifiers. This slashes control panel heat generation, reduces control circuit sizing requirements and improves overall system reliability—a decisive advantage in high-density motor control centers.420 A IEC heavy-current switching capacity:The Allen-Bradley 100-D420EA00​ is purpose-built for the upper echelon of motor control duties, delivering a rated operational current of 420 A in AC-3 service and switching motors up to 425 kW at 690 V AC. Its breaking capacity reaches 8–10× Ie, allowing safe make/break of high inrush inductive loads such as crusher motors, compressor drives, large pump starters and mining conveyor systems. The silver-alloy (Ag-CdO) main contacts resist welding and arc erosion, contributing to a mechanical life exceeding 5 million operations and an AC-3 electrical life of over 1 million operations.Panel-mounted industrial ruggedness:Strictly engineered for panel screw mounting (the 420 A frame precludes DIN rail installation), the Allen-Bradley 100-D420EA00​ presents a robust, vibration-resistant architecture weighing 7.5–8.2 kg. Its screw terminals accept 4 AWG–350 kcmil copper conductors, ensuring secure, low-resistance connection to bus bars or cable lugs. IP20 terminal protection, VDE 0106-compliant finger and hand-back protection, and a -25 °C to +60 °C operating range guarantee safe, reliable operation in demanding industrial environments—from frigid mining sites to tropical processing plants.Modular auxiliary contact system:While the base 100-D420EA00​ unit carries no built-in auxiliary contacts (the “00” suffix), it fully supports side-mounted auxiliary contact blocks (e.g., 1NO+1NC or 2NO+2NC configurations). This modularity allows engineers to customize the contactor for specific interlock, feedback signaling and state indication needs without overspecifying the device or paying for unused built-in contacts. Add-on surge suppressors, mechanical interlocks, IP20 terminal guards and bus connection kits further tailor the Allen-Bradley 100-D420EA00​ to the exact application.Coordinated short-circuit protection:Validated to IEC 60947-4-1 Type 2 performance, the Allen-Bradley 100-D420EA00​ is fully coordinated with upstream short-circuit protection devices—560 A BS88 fuses at 415 V / 65 kA available fault current, or 500 A gG/gL DIN fuses at 690 V / 50 kA. This ensures that under a downstream short circuit, the contactor’s contacts survive without welding, the fuse clears the fault, and the motor circuit is restored after a simple fuse replacement rather than requiring contactor substitution. For UL/CSA applications, the contactor is rated for 1000 A Class L fuses at 600 V / 18 kA, satisfying UL 508 and CSA 22.2 No.14 requirements.Global compliance and certification:The Allen-Bradley 100-D420EA00​ carries a comprehensive certification portfolio—UL 508, CSA 22.2, CE, CCC and RoHS—making it deployable across North American, European, Chinese and global industrial markets without recertification. Combined with its IEC 60947-4-1 compliance and 2000 m altitude rating, the contactor is equally at home in a Houston petrochemical plant, a Swedish pulp mill, a Chinese water treatment facility or an Australian mining operation.Discontinued-but-supported lifecycle value:Although Rockwell Automation announced the discontinuation of the Allen-Bradley 100-D420EA00​ effective March 31, 2019, the installed base of 100-D420 panels remains vast across global industry. Our inventory of genuine original Czech-manufactured units provides plant engineers with a drop-in spare that preserves the entire existing control architecture—avoiding the substantial cost, downtime and engineering effort of migrating to the 100-E400ED11 replacement platform.
